Adding Multiple accounts in Mozilla Thunderbird
Like Firefox You can add profiles in Thunderbird.

-no-remote option is required to start a new instance, if another is already running).
Now we have a default profile, In order to create a another account create a profile and remember.
Once created one or more profiles, to start with a given profile you can create a launcher with the following command
